By disabling Watson, nothing really changes from the user's point of view. The programs still crash, and you still get a dialog box saying so. It's not the Watson dialog box offering to report the problem; it's the old-school dialog. You get a box, you have to click, there's no avoiding it.

What the user really wants is for the programs to stop crashing in the first place. To get that, you need to keep Watson enabled, and click on the Send button. We use the data, we really do! We're fixing bugs!

You might on occasion get a response telling you about a new version (with bug fixes) or a workaround. If you don't click on Send, you surely won't.
